Former UFC women's bantamweight champion Ronda Rousey didn't announce her retirement from MMA, but from what she did say, fans shouldn't expect to see her in the octagon again.

"I don't know. I think it's just as likely as me going back to another Olympics for judo," Rousey said when asked on "The Ellen Show" about her possible return to the UFC. "No one demanded a written resignation from me for judo and I don't really think the same thing is necessary for fighting."

Before beginning her MMA career in 2011, Rousey represented the United States at the 2008 Olympics in judo where she claimed a bronze medal.

Rousey is now a member of World Wrestling Entertainment (WWE).

Rousey began her MMA career with 12 consecutive stoppage wins. Eleven of those stoppages came in the first round. During that run, Rousey defended the UFC women's bantamweight title six times. Her first loss came in her seventh attempted title defense. Holly Holm knocked Rousey out with a head kick in that November 2015 contest. Rousey returned to the octagon in December 2016 when she faced current champion Amanda Nunes. Nunes made quick work of Rousey. She knocked out the former champion in 48 seconds.

In November, UFC President Dana White told MMAjunkie that he did not want to see Rousey compete in MMA again.
